Assessment of MRI Tractography for Pelvic Floor Sphincter Analysis
Urinary and faecal incontinences generally come from a dysfunction of the pelvic floor muscles, and more particularly the sphincters. Among other causes, they may be related to accidental trauma, obstetric or iatrogenic. On this last point, the incidence of surgical interventions on the bladder collar and on the anal canal on the prevalence of incontinences can be underlined. MRI tractography could be an interesting tool to visualize in 3D the structure of pelvic sphincters and their lesions. It may thereby establish the link with observed dysfunctions, thus potentially providing a complement to the urological and proctographic examinations already carried out. The objective of this study is, first, to define the sensitivity of the MRI tractography for the visualization of the pelvic sphincters architecture regardless of the gender. In a second time, it will give a description of normal and abnormal (pathological cases) tractography, as well as a descriptive post-surgery. The other interest of this study is the assessment of the information provided by pelvic sphincters tractography on a panel of various and frequently encountered situations in clinical routine at the IHU.
